"It strengthens the prohibitions against solicitation of Medicaid clients," Nelson said. "We heard story after story about that. We are going to prohibit that and make sure it doesn't take place."

So far, the bill does not specifically prohibit handing out gifts and cash to parents to induce them to take their children to certain dentists. Nelson says hearings over the next two months will flesh the bill out.

The legislation also articulates the Inspector General's role in uncovering and reporting fraud, and bans a dentist from participating in Medicaid if found guilty of fraud.

The bill moves Medicaid Transportation into managed care, and directs the Department of Health and Human Services to reduce inappropriate ambulance use.

Even though the specifics of this bill haven't yet been hammered out, there's already huge opposition to it. That's a sign, Nelson says, that as it is, some dentists are making lot of money.
